It's a nice little test sandbox environment, but not a "game", per se.
I was so excited when I saw that this was like Alan Wake. The only thing that's really like Alan Wake is using the light to "clear the darkness" and then the gun to shoot them. Also, yes, this wasn't 64x64 and it didn't have much to it other than 1 player and 1 enemy that just immediately respawns on death.
